To all whom it may concern.' ,l i p .p

Be it known thatI, RALPH R. RrorrAIm-` SON, a citizen of theUnitedStates, and-a A resident` of Chicago, countyofCook, and State ofIllinois, have 'invented'certain new and useful Improvements inFoldinr'Paper Boxes, of which the followingis a yfu lcle'ar, and exactdescription. l

The invention relates. to folding .paperl boxes and seeks to provide asimple, strong construction which can be economically manufactured' and.which canfbe shippedk in collapsed or knock-down form.-` y Theinvention consists the-features'of improvement hereinafter Yset forth,illustrated in the preferred forms in the accompanying drawing and `moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a view of the* blank from which theimproved boX is formed. Fig. 2 is a perspective view illus trating themanner of folding the parts of the box. Fig. 3 is a perspective viewofthe complete box with the cover or lid open.`

Fig. 4 is a cross-section of the complete box with the lid closed. Figs.5 and 6 are views similar to Figs. 3 and 4, respectively, illustratingthe modified form.

The improved box comprises a bottomv wall a, opposite end walls b and cand oppo.

site side or front and rear walls d and e. Scored portions 1 form thevertical corners of the box and connect the opposite side and end walls.The side or rear wall elis provided at its end with an integral` foldingtab or flap 2, which is connected thereto by one of the verticalscores 1. The opposite end walls are provided at their upper and loweredges with integral folding flaps 3 and 4 which are connected thereto byhorizontal scores 5. The upper end flaps 3 are quite narrow, while thebottom end flaps 4 are of considerable width. In the form shown, thenarrow, upper `end flaps 3 are provided with scalloped edges. p tomwall. a is formed integral with the side or front wall d and isconnected thereto by the horizontal scored portion 6. The bottom has anintegral extension. f connected to its opposite or rear edge by thehorizontal score 7 and the extension f is provided with the foldingportion g connected thereto by a horizontal score 8. In the preferredform of the invention shownin Figs. 1 to 4, inclusive, the part g formsthe cover of the box and is provided at its free edge with an inte- Thebotthereto by a horizontal score 11.y

Aa; r e... naar as ,forma,@samen im Fig. 1, the end `wall and the rearWalla?` are `folded upon the .end wall .a and front wall fd, and the`tab "orf flap` @is pasted `to the inner face ofthe edge portion: of the`end `wall c.' The parts f and g can then be folded upwardly aboutythegscoredline 7 and the box y shipped, in` collapsed condition. Infoldin'gfthe box for`,use',lthe"side `and end walls arerseparated: andthe iaps and 4 i folded inwardly es Shown n Fig 2. The zbitorn `aisthen. foldedtupwardlyl against 5 the bottom. end; `flaps 4` and` theextensen4 f yand portion g thereon are turned up and are passed betweenthe rear walle andthe inturned end""liapisi`i3 `and' 4. To facilitatethe passage of the extension f, the part g 10 between the rear wall eand and the flap the flaps 4, the rear edges 12 of the latter arepreferably` inclined or cut away,` as

tension f snugly against the inner face of the side or rear wall e andthe folding portion g overlaps the upper end flaps 3, so that theextension f and folding bottom a are securely held in position.

In the preferred form shown in Figs.,1 to 4, inclusive, the foldingportion g forms `the cover of the box and the liap `10 at its outer edgeis adapted to sbe inserted between the forward edges of the upper endaps 3 and the front d of the box to hold the cover closed, as shown inFig. 4. To facilitate opening the box, the upper edge of the front wallis referably provided with a notch 13.

The orm shown in Figs. 5 and 6 is simi` lar to that shown in Figs. 1 to4, inclusive,

shown. The end flaps 3 and 4 hold the eX- except that the foldingportion g at the upper end of the extension f is quite nar-` row and, inthe form shown, its forward edge is scalloped. This portion g overlapsthe upper end flaps 3 and holds the extension f and folding bottom a inposition. In this `form of the invention the cover h is connected to theupper edge of the rear wall e and is preferably formed integraltherewith. Like the cover portion g of the form shownin Figs. 1 to 4,inclusive, the cover z is provided with a flap 10 at its outer edgearranged to be inserted between the front wall and the upper end flaps3.

The construction can be economically manufactured and shippedin'collapsed form.

When the parts are opened and folded, as

described, a strong, rigid covered box is provided. l f y ItI should benoted that vthe folding bottom cannot be pushed into the box` because itoverlaps the lower Haps 4 of the endwalls and is held againstbeingdepressed Aby the inturned portion" of the extension fwhi'ch overlapsthe upper flaps 3 of the end walls. In -the 4preferred form, as shown,the iaps 4 extend inwardly to a point substantially midway between thevend walls, so thatl a u strong, double bottom is provided for the fnected to the lower edge of one of said side l Copies of this patent maybe obtained for walls and overlapping said lower end flaps and having anupturned extension arranged `between the opposite side wall and saidupper and lower end iaps, said extension having an inwardly foldedportion overlapping said upper end flaps, substantially as described.

. 2. A folding paper box comprising connected front, end and rear walls,said end walls having inturned Haps at their upper and lower edges, anda folding bottom connected to the lower edge of said front wall andoverlapping said lower end aps and having an upturned extension at itsrear edge arranged between said rear wall and said upper and lower endflaps, said extension having an inwardly folded portion forming a coverfor the boX and arranged to overlap said upper end Haps, substantiallyas described.
